AIR COOLER AND REFRIGERATOR.

Application filed April 27,

This invention relates to a refrigerating device and pertainsparticularly to a devlce designed especially for cooling the air of aroom or a building.

The primary object of the present inventions is to provide a new andnovel as well as efficient means for effecting the lowering oftemperature in homes, public buildlngs and other places where such'lowerlng of the temperature is desirable.

The invention broadly contemplates the provision of a cabinet housing, acompressor, an air circulating fan and a refrlgerating fluid containingunit having means whereby air may be circulated in close proximlty tothe fluid to be cooled thereby.

Numerous other objects and advantages of the present invention willbecome apparent from a consideration of the following detaileddescription taken in connection wlth the accompanying drawings forming apart of this specification with the understanding, however, that theinvention is not'confined to any strict conformity with the showing ofthe drawings but may be changedor modified so long as such changes ormodifications mark no material departure from the salient features ofthe invention as expressed in the appended claims.

In the drawings:

Fig. 1 shows a vertical longitudinal section through the structureembodying the present invention.

Fig. 2 is a front elevation of the refrigerating fluid containing unit.1

Fig. 3 is a top plan view of the fluid containing unit.

Referring now to the drawings more in detail wherein like numerals ofreference indicate corresponding parts throughout the several views, thenumeral 1 indicates generally the structure embodying this invention. Asshown, the same comprises a cabinet 2 having transverse horizontalpartitions 3 and 4 dividing the same into upper, intermediate and lowercompartments 5, 6 and 7 respectively.

The upper part of the back wall of the cabinet is provided with thelouvre 8 to permit passage of air thereinto and into the pipe 9, leadingto the blower fan 10, which fan is run by a motor 11, the speed of whichmay be varied through manipulation of the controlling rheostat 12. Theair current created by the fan 10 is discharged through an open- 1927.Serial N0. 187,076.

ing 13 cut in the partition 3, into the intermediate compartment orchamber 6.

Within the chamber 6 there is placed a cooling unit indicated as a wholeby the numeral 14, which unit is of substantially L- shaped crosssectional design and comprises a closed tank 15 having a plurality ofair tubes 16 incorporated therein and extending vertically therethrough.In the upper portion of the tank 15 a header 17 is positioned which hasattached thereto a number of coolin coils 18. Through the header 17 andcoils 18 a refrigerant circulates which circulation is maintained by acooler and compressor 19 located in the lower compartment and from whichthe pipes 20 lead to the header 17, as shown. Since the compressor 19forms no part, in itself, of the present in vention and any suitabletype may be employed, no detailed description thereof will be given.

The front portion of the unit 14 may be provided with a tray or stand 21upon which articles of food may be placed if desired and beneath theunit is located a tray 22 to receive foreign matter which might enterthe tubes of the unit.

The front wall of the cabinet 2 is provided with a door 23 provided withthe louvre 24 over which, upon the inside, a cover 25 may be placed whenit is desired to stop the flow of cool air from the structure.

In the top of the unit 14 an expansion tube 26 is mounted into which thefluid of the tank 15 can rise when the same warms. In order to purifythe air passing through the pipe 9, the tubes 16, and out of the louvre24, an ozonizing device 27-of any desired construction may be fitted inthe inlet pipe 9 to act on the air passing therethrough.

The front of the upstanding portion of the tank 15 extends upwardly toengage the underside of the partition 3 as indicated at 28 and by reasonof this the air passing through the inlet opening 13 will be forced totravel downwardly through the tubes 16 in the rear portion of the tankbefore it can flow upwardly through the tubes in the front of the tankand out through the louvre 24.

It is apparent from the description of the invention as above given thatthe forced circulation of air through the air tubes 16 will cause thetemperature of the room in which the device is located to drop veryrapidly. Furthermore, circulation of the air through the cooling unitwill tend to dpurify the same, since all germs, bacteria, an other suchforeign matter in the air will, when cooled, cling to the sides of thetubes. This accumulation of germs and the like may, from time to time,be removed and taken out in the pan 22.

Having thus described my invention, what I claim is: r

1. In combination, a cabinet having an upper, an intermediate and alower compartment, a cooling unit in said intermediate compartmenthaving means to permit air to flow therethrough, an air circulatingstruc-' ture in said upper compartment designed to force air downwardlythrough said unit, cool air escape means opening from said intermediatecompartment, and means in said lower compartment for supplying arefrigerant to said unit.

2. In combination, a cabinet having an upper, an intermediate and alower compartment, a cooling unit in said intermediate compartmenthaving means to permit air to flow therethrough, an air circulatingstructure in said upper compartment designed to force air downwardlythrough said unit, cool air escape means opening from said intermediatecompartment, and means in said lower compartment for supplying arefrigerant to said unit, a door leading into said intermediatecompartment, and means to provide an article support upon said unit.

3. An air cooling structure comprising a liquid refrigerating unit ofsubstantially L- shaped cross sectional design, tubular bodiessurrounded by the liquid of said unit, means for driving air thru saidbodies for cooling, means whereby air Will be caused to traveldownwardly in the longer portion of the unit and upwardly thru theshorter portion of the ,unit, and means to provide an article supportupon said shorter portion. p

In testimony whereof I affix my signature.
